    摘要: Subject matter of the present invention is a drilling fluid additive based on sulfonated asphalt, which comprises a water soluble and anionic polymer component in quantities of 0.1 to 20 wt. %, with respect to the total additive in addition to the asphalt component. With this additive the water solubility of sulfonated asphalt can be markedly increased. This additive, whose polymer component is thermally highly stable, is utilized primarily in water- and/or oil-based drilling fluids and in particular in the exploration of subterraneous petroleum and natural gas deposits. Typical polymer components to consider are representatives of polycondensation products, such as phenol resins, ketone resins and sulfonated naphthalene, acetone and amino plasticizer resins (for example urea and melamine resins).

    摘要: Methacrylate derivatives are added to salt-containing media to thicken the media, and are particularly useful in the exploration of mineral oil or natural gas deposits. The salt-containing media have a specific density of 1.2 to 2.5 kg/l. The respective methacrylate derivatives, which may be, e.g., mono- and/or difunctional variants, have been found to be particularly suitable, are used in a volume ratio of 100 to 1:1 and an amount of 0.5 to 15% by volume. The thickening of the salt-containing media is effected primarily as gel formation, which can be carried out with the aid of free radical initiators and at elevated temperatures. In particular, completion brines, drilling and drill-in fluids and fracturing fluids and acids having high salt contents are to be regarded as aqueous media. The methacrylate derivatives have a markedly good solubility in heavy brines, as are used primarily in upstream processes of the oil industry. They can also be polymerized subterraneously, and they simultaneously have a high thermal stability.

    摘要: The use of dicarbonyl compounds for increasing the thermal stability of biopolymers in aqueous liquid phases in petroleum and natural gas exploration is claimed. The biopolymer component preferably comprises polysaccharides prepared by fermentation, such as, for example, scleroglucan or welan gum. The aqueous liquid phase is typically a drilling fluid which may also contain high salt concentrations (“brines”). Glyoxal may be mentioned as a particularly suitable member of the dicarbonyls. It can either be admixed with the liquid phase or preferably also be incorporated in the course of the preparation of the biopolymer. The use according to the invention shows their advantages, particularly at temperatures in the rock formation which are above 250° Fahrenheit.

    摘要: A novel method for breaking the viscosity of an aqueous phase thickened with preferably hydrophilic polymers in the exploration and production of mineral oil and/or natural gas is proposed. For this purpose, the breaking is carried out via the formation of a low-viscosity emulsion, with water as the continuous phase, this emulsion being formed by the addition of at least one surface-active component to a system which consists of the thickened drilling fluid and an oil phase which is crude oil present in the reservoir and/or oil introduced into the reservoir. Solubilizers between oil phase and water phase and in particular non-ionic surfactants, cationic surfactants and/or amphoteric surfactants are used as a preferred surface-active component. In addition to the surface-active component, it is possible to use further components, which are demulsifiers, non-emulsifiers, co-surfactants or surface tension modifiers. With the aid of this method, with the simultaneous presence of an oil phase, the aqueous phase can be displaced as a low-viscosity system and finally discharged at the surface, extremely effective cleaning of the well being associated therewith. With regard to the cost-efficiency and from an environmental point of view, the use of chemicals can be completely dispensed with.

    摘要: A method for the rheology control of fluid phases, in which adducts which contain layered mixed metal hydroxides (MMH) and hectorite are used, and corresponding compositions for this purpose are claimed. Preferably used MMH are those which were produced by hydration of mixed metal oxides or oxyhydroxides, which in turn may be thermally activated. The use of coprecipitated MMH or of MMH produced in situ is also possible. The ratio of MMH to the hectorite component should preferably be from 0.05 to 0.2:1, it also being possible to use adducts whose clay fraction contains up to 80%. by weight of clays differing from hectorite, in particular bentonite. The method is preferably carried out using drilling fluids in the high-temperature range >300° F. (>149° C.).

    摘要: This process for the preparation of homogeneous, low-viscous and long-term-stable polymer dispersion in mineral oils, in which a liquid mineral oil component, to which a water-soluble polymer and an organophilic bentonite have been added, is stirred, is distinguished by the fact that the dispersing process is carried out at speeds of ≧1000 rpm. The duration of the stirring operation should preferably be between 5 and 60 minutes, and both aromatized and/or dearomatized mineral oils and also as typical water-soluble polymers, which moreover may have a maximum water content of 25% by weight, can be used. By means of this relatively simple process, homogeneous polymer-containing mineral oil dispersions having a low viscosity and at the same time pronounced long-term stability, which are suitable in particular for use in oil and gas exploration, are obtained in very short mixing times.
